“…Alfvén became one of the most vocal spokesmen about the impact of DL on astrophysical objects and cosmology [Alfvén, 1977[Alfvén, , 1982[Alfvén, , 1990. Others did more direct applications to regions such as the solar corona providing alternative methods to the BGK solution and further improvements of the theoretical descriptions [Montgomery and Joyce, 1969;Block, 1972;Swift, 1975;Perkins and Sun, 1981;Williams, 1986;Sato and Miyawaki, 1992;Boström, 2004].…”

Localized, quasi-static parallel electric fields that are created as a result of charge separation in plasmas have been studied by scientists over the last century and have become known as double layers (DLs). DLs are important because they can efficiently accelerate charge particles, dissipate energy, and cause a local break in the frozen-in condition. As a result, they are expected to be an important process in many different types of space plasmas on Earth and on many astrophysical objects. This paper presents a brief review of the history of DLs over the last century leading to the now well-established fact that they do occur naturally in space plasmas. The paper also presents some of the latest understanding of the basic properties of DLs in the aurora region and discusses some open research questions.
